    I'm looking vor the wirering informatio for the jumpers.

    At the moment I have a RX211 controller for RX02 drive. On the PCB the jumper is missing.
    I think the normal interrupt priority here is BR5.

    Where can I get wirering informations?

    regards

    maintenance prints are available at http://bitsavers.org/pdf/dec/unibus/MP00626_RX211_Dec78.pdf

    looks like you're interested in E24, which is in the lower right corner of sheet 3 of the schematics,
    page 12 of the PDF file.

    Thank's to roger

    So the solder iron and a DIL 16 socket with some wires will solve the problem.

    On my RX211 that was missing the plug, I just used a machine pin DIP16 socket with some breadboard jumper wires plugged into it. No soldering. Connections:

    2-7 BG5i-BGi 500mil
    3-6 BGo-BG5o 300mil
    4-5 BG4i-BG4o 100mil
    8-9 BG6i-BG6o 300mil
    10-11 BG7i-BG7o 100mil
    12-14 BR5o-BRo 200mil
